DETAILED DESCRIPTION

Aspects of the present disclosure are directed toward automated medical assistance and, more specifically, to providing automated medical assistance to passengers in autonomous, semi-autonomous, and/or non-autonomous vehicles. While the present disclosure is not necessarily limited to such applications, various aspects of the present disclosure may be appreciated through a discussion of various examples using this context.

In accordance with some embodiments of the present disclosure, medical assistance can be provided in a vehicle based on information derived from a network of sensors in an Internet of Things (IoT) configuration. In embodiments of the present disclosure, the IoT can be a network of physical devices having electronics, hardware, software, sensors, actuators, and/or network connectivity and configured to generate data, share data, and implement actions based on the shared data. The physical devices can include, but are not limited to, cameras (e.g., visual/audio cameras, thermal cameras, etc.), microphones, heart rate monitors, blood pressure monitors, wearable devices, pedometers, directional thermometers, odor sensors, moisture sensors, air composition sensors, accelerometers, medical devices, diagnostic devices, and so on. The physical devices can further include vehicular devices such as, but not limited to, navigation equipment, environmental controls, and communication equipment. The physical devices can further include other physical devices such as, but not limited to, traffic sensors (e.g., traffic lights, congestion sensors, traffic cameras, etc.), mobile emergency unit sensors (e.g., locations of ambulances), and so on.

Aspects of the present disclosure monitor one or more passengers in a vehicle using a vehicular medical assistant. The vehicular medical assistant can monitor passenger health using one or more sensors. The vehicular medical assistant can use cognitive computing (also referred to as machine learning algorithms herein) to identify a medical event (e.g., choking, heart attack, nausea, etc.) based on the data collected from the one or more sensors and compared with information in a medical data store. The vehicular medical assistant can execute one or more actions and/or one or more interactions in response to detecting a medical event. Actions can include, but are not limited to, rerouting the vehicle, stopping the vehicle, notifying an emergency authority, and so on. Interactions can include, but are not limited to, providing instructions to the passenger, attempting to wake an unconscious passenger, providing a medical aid to the passenger (e.g., a bandage, an antiseptic, a disinfectant, a medication, a vomit bag, an epinephrine autoinjector, an opiate antidote, an inhaler, etc.), communicating with the passenger, and so on.

Aspects of the present disclosure realize numerous advantages such as, but not limited to, increased vehicular safety. For example, in non-autonomous vehicles, aspects of the present disclosure can determine a driver is falling asleep and wake the driver, communicate with an emergency authority during a medical event, and/or provide medical instruction to one or more passengers. In semi-autonomous vehicles, in addition to the safety advantages discussed above for non-autonomous vehicles, aspects of the present disclosure can safely stop a car if a driver is temporarily disabled (e.g., if a driver has a seizure while driving, a semi-autonomous vehicle can temporarily control the vehicle to stop the vehicle on the side of the road). In autonomous vehicles, in addition to the safety advantages discussed above for non-autonomous vehicles and semi-autonomous vehicles, an autonomous vehicle can reroute the vehicle to an emergency center (e.g., hospital, urgent care center, fire station, police station, etc.) during a medical emergency. Thus, aspects of the present disclosure improve passenger/driver safety in non-autonomous, semi-autonomous, and/or autonomous vehicles.

As a second example advantage, aspects of the present disclosure employ cognitive learning to increase the accuracy of detected medical events and increase the effectiveness of mitigation actions executed in response to detecting a medical event. Cognitive learning is uniquely suited to the field of medical event detection and mitigation due to the complicated relationships between medical measurements, symptoms, conditions, risks, and mitigation techniques. As one example illustrating the advantages of cognitive learning over predefined, static rules, a blood pressure reading of 145/96 may be a highly elevated and abnormal reading for a first person, while a blood pressure reading of 145/96 may be consistent with a second person's average blood pressure reading. Thus, the blood pressure measurement for the first individual may indicate an acute medical emergency, while the same blood pressure measurement associated with the second individual may indicate a chronic health condition rather than an acute medical emergency. To differentiate the acute medical emergency from the chronic health condition, aspects of the present disclosure can account for other factors such as, but not limited to, heart rate, temperature, pupil dilation, perspiration, gesticulation analysis, aural indications (e.g., groaning, retching), natural language processing (e.g., a response to a question “are you feeling ok?”), and so on. Thus, cognitive learning advantageously improves a vehicular medical assistant based on the capability of cognitive computing to identify multivariate indicators, factors, and/or correlations between large amounts of aural data, biometric data, visual data, and/or environmental data, thereby improving accuracy of identified medical events and improving passenger health outcomes associated with implemented mitigation actions.

Thus, aspects of the present disclosure exhibit numerous advantages. However, not all advantages are listed, and aspects of the present disclosure exist that can contain, all, some, or none of the aforementioned advantages while remaining within the spirit and scope of the present disclosure.

Referring now to FIG. 1, illustrated is a block diagram of an example IoT environment according to aspects of the present disclosure. The IoT environment can include numerous components communicatively coupled by a network 150 such as, but not limited to, a vehicular medical assistant 102 located in a vehicle 100, a medical data store 120, an emergency service 130, a traffic service 132, a mobile emergency unit 134, and a passenger device 136.

Vehicle 100 can comprise a non-autonomous vehicle, a semi-autonomous vehicle, or an autonomous vehicle according to various embodiments. Vehicle 100 can be a sedan, sport-utility-vehicle (SUV), truck, bus, all-terrain vehicle (ATV), aerial vehicle (e.g., plane, helicopter, etc.), train, ship (e.g., ferry, cruise liner, etc.), or a different form of vehicular transport.

Vehicle 100 can include a vehicular medical assistant 102 configured to detect and mitigate medical events experienced by a passenger in vehicle 100. Although vehicular medical assistant 102 is shown within vehicle 100, vehicular medical assistant 102 can likewise be communicatively coupled to, but physically removed from, vehicle 100. For example, in some embodiments, aspects of vehicular medical assistant 102 can be provided as a service to vehicle 100 and utilize existing technology within vehicle 100 such as a display interface, autonomous or semi-autonomous driving technology, speakers, and other aspects of vehicle 100 to virtually provide aspects of vehicular medical assistant 102. In some embodiments, vehicular medical assistant 102 comprises a discrete unit physically integrated into vehicle 100 (e.g., integrated into the vehicle during assembly, or attached as an after-market accessory).

Vehicular medical assistant 102 can include aural sensors 104 collecting aural data from a passenger in the vehicle 100, biometric sensors 106 collecting biometric data from the passenger in the vehicle 100, visual sensors 108 collecting visual data from the passenger in the vehicle 100, and environmental sensors 110 collecting environmental data from the vehicle 100. Vehicular medical assistant 102 can further include cognitive learning instructions 112 configured to learn (e.g., identify, quantify, and/or model) interrelationships between diagnostic data, medical conditions, and mitigation actions. Vehicular medical assistant 102 can further include detection instructions 114 configured to detect a medical event and mitigation instructions 116 configured to mitigate a medical event. Vehicular medical assistant 102 can further include a user interface 118 for verbally, textually, and/or visually interacting with a passenger in vehicle 100.

Aural sensors 104 can be sensors configured to detect sounds such as speech, choking sounds, retching sounds, coughing sounds, breathing levels (e.g., hyperventilation), groans, and so on. In some embodiments, aural sensors 104 can be calibrated to detect sounds from an area defined by a direction and a range. In some embodiments, aural sensors 104 can be calibrated to detect sounds within a certain frequency range (e.g., 20-20,000 hertz) and/or within a certain volume (e.g., 0-130 decibels).

Biometric sensors 106 can include active sensors and passive sensors. Active sensors are sensors requiring user interaction to derive medical information from the user. Active sensors can include, but are not limited to, some blood pressure monitors (e.g., measured by a pressurized cuff on a passenger's arm), some heart rate monitors (e.g., contacting a passenger on the chest, wrist, palm, finger, or a different location), and some blood sugar level monitors (e.g., requiring blood sampling using a lancet). Passive sensors are sensors collecting medical information from a user without requiring user engagement and/or action. Passive sensors can include, but are not limited to, thermometers (e.g., directional thermometers, thermal video cameras, etc.), odor sensors (e.g., chemosensors, sensors utilizing gas chromatography, etc.), and other sensors.

Visual sensors 108 can include video cameras capable of capturing passenger behaviors (e.g., movements, gesticulations), color variation (e.g., pale, flushed, etc.), perspiration (e.g., changes in facial reflectivity), pupil dilation, blinking (e.g., blinks per minute, eyes closed, etc.), breathing (e.g., breaths per minute, intensity of breathing, etc.), and other conscious and unconscious behaviors which may be indicative of a passenger's health.

Environmental sensors 110 can include sensors measuring temperature, humidity, oxygen content, acceleration, and/or other features of the passenger area. Environmental sensors 110 can include, but are not limited to, a thermometer, a humidity sensor, an accelerometer (e.g., measuring passenger position in a seat), an air composition sensor, and other sensors.

Cognitive learning instructions 112 can include processor-executable instructions for ingesting a medical data store 120 and generating correlations, associations, interrelations, predictions, expectations, confidence-levels, thresholds, algorithms, models, and/or other insights related to detecting and mitigating a medical event. In some embodiments, cognitive learning instructions 112 are configured to generate medical event index 128.

Detection instructions 114 can include processor-executable instructions for detecting a medical event based on the data collected from aural sensors 104, biometric sensors 106, visual sensors 108, and/or environmental sensors 110. Detection instructions 114 can include instructions for matching a set of collected data to a known combination of data indicating a medical event. In some embodiments, detection instructions 114 rank, score, or otherwise approximate an urgency associated with the detected medical event.

Mitigation instructions 116 can include processor-executable instructions for mitigating the medical event. Mitigation instructions 116 can include instructions for interacting with the passenger via a user interface 118, rerouting the vehicle carrying the passenger, altering the environmental conditions of the vehicle carrying the passenger, notifying an emergency authority, and/or other mitigation actions.

User interface 118 can be a user interface capable of presenting questions to a passenger (e.g., verbally and/or visually) and collecting feedback from the user (e.g., verbal feedback, movement-based feedback, and/or tactile feedback).

Vehicular medical assistant 102 can be connected to medical data store 120 via network 150. Medical data store 120 can store structured, semi-structured, and/or unstructured medical data relevant to detecting and mitigating a medical event in the vehicle 100. Medical data store 120 can include diagnostic data 122, medical conditions 124, mitigation actions 126, and medical event index 128. Diagnostic data 122 can comprise numeric and/or textual measurements indicating normal and abnormal health conditions. In some embodiments, diagnostic data 122 includes data similar in nature to the data collected by aural sensors 104, biometric sensors 106, visual sensors 108, and/or environmental sensors 110.

Medical conditions 124 can comprise various combinations of diagnostic data indicating various medical conditions. For example, the medical condition 124 “unconscious” could be associated with diagnostic data 122 of eyes closed, a slumped posture, and unresponsive to interaction as detected by visual sensors 108. As another example, the medical condition 124 “choking” could be associated with diagnostic data 122 of “hands at throat” as detected by visual sensors 108 and coughing as detected by aural sensors 104. As another example, the medical condition 124 “fever” could be associated with diagnostic data 122 of three consecutive thermometer measurements on a passenger's forehead above 100° Fahrenheit as measured by biometric sensors 106. As another example, the medical condition 124 “mirror cut on hand” could be associated with diagnostic data 122 collected from visual sensors 108 and biometric sensors 108.

Mitigation actions 126 can be executed at the vehicle using mitigation instructions 116. Mitigation actions 126 can include, but are not limited to, rerouting the vehicle, changing environmental conditions in the vehicle cabin, interacting with the passenger, dispensing a medical aid to the passenger, and/or contacting an emergency authority on behalf of the passenger.

Medical event index 128 can interrelate the diagnostic data 122, the medical conditions 124, and the mitigation actions 126. Thus, medical event index 128 can be used to determine an appropriate mitigation action 126 for given diagnostic measurements 122 and/or given medical conditions 124.

Vehicular medical assistant 102 can also be communicatively coupled to emergency service 130 via network 150. Emergency service 130 can be an emergency authority such as, but not limited to, dispatchers associated with a police department, fire department, emergency medical service (EMS) department, hospital, a clinic, a regional authority (e.g., city, county, region), or a different dispatch service. Emergency service 130 can receive information from, and provide information to, the vehicular medical assistant 102.

Vehicular medical assistant 102 can also be communicatively coupled to traffic service 132 via network 150. Traffic service 132 can include traffic congestion information and/or traffic shaping functionality that may be used to plan routes, estimate arrival times, and/or change routes in real-time for the vehicle 100 in response to a medical event.

Vehicular medical assistant 102 can also be communicatively coupled to mobile emergency unit 134 via network 150. Mobile emergency unit 134 can be, but is not limited to, an ambulance, a fire truck, a police vehicle, or a different vehicle capable of resolving a medical event and/or facilitating transfer of a passenger to a hospital.

Vehicular medical assistant 102 can also be communicatively coupled to a passenger device 136. Passenger device 136 can comprise a wearable device, a health monitoring device, a mobile phone, a tablet, or a different device. Passenger device 136 can store passenger data 138. In some embodiments, passenger data 138 comprises historical health data of the passenger (e.g., average heart rate, health conditions, medications, risk factors, etc.).

Network 150 can comprise any physical or virtual network, including Wi Fi, broadband, cellular, short-range, and/or other networks. Although a single network is shown, multiple similar or dissimilar sub-networks may likewise be used to continuously or intermittently connect various components illustrated in FIG. 1.

FIG. 1 is intended to represent the major components of an example IoT environment according to embodiments of the present disclosure. In some embodiments, however, individual components can have greater or lesser complexity than shown in FIG. 1, and components other than, or in addition to those shown in FIG. 1 can be present. Furthermore, in some embodiments, various components illustrated in FIG. 1 can have greater, lesser, or different functionality than shown in FIG. 1. Further still, aspects of the present disclosure exist comprising only a subset of the components illustrated while remaining within the spirit and scope of the present disclosure. As one example, in some embodiments, only vehicular medical assistant 102 and medical event index 128 are used to implement aspects of the present disclosure.

FIG. 2 illustrates a flowchart of an example method for managing a medical event in accordance with some embodiments of the present disclosure. In some embodiments, the method 200 is executed by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10), by a processor, or by a different set of hardware and software resources. For clarity, the method 200 will be described as being executed by a vehicular medical assistant, however, the method 200 can likewise be performed by alternative configurations of hardware.

In operation 202, the vehicular medical assistant can access a medical data store (e.g., medical data store 120 of FIG. 1). The medical data store can comprise diagnostic data, medical conditions, and mitigation actions useful for detecting and mitigating a medical event in a vehicle. The medical data store can further comprise interrelationships between diagnostic data, medical conditions, and mitigation actions. In some embodiments, the interrelationships are identified, quantified, and/or modeled using machine learning algorithms executed on the medical data store. The machine learning algorithms can generate additional information (e.g., definitions, algorithms, computations, insights, correlations, indications, analyses, or other interrelationships) useful for monitoring passenger health, detecting a medical event, and mitigating a detected medical event. Operation 202 is described in further detail hereinafter with respect to FIGS. 3, 4, and 5A-5C.

In operation 204, the vehicular medical assistant can detect a medical event. The medical event can be detected based on a set of data associated with a passenger in a vehicle and the medical data store accessed in operation 202. In some embodiments, the set of data associated with the passenger in the vehicle comprises aural data from the passenger and collected by one or more aural sensors (e.g., aural sensors 104 of FIG. 1), biometric data from the passenger and collected by one or more biometric sensors (e.g., biometric sensors 106 of FIG. 1), visual data from the passenger and collected by one or more visual sensors (e.g., visual sensors 108 of FIG. 1), and/or environmental data of the vehicle cabin and collected by one or more environmental sensors (e.g., environmental sensors 110 of FIG. 1). Operation 204 is described in further detail hereinafter with respect to FIGS. 6-7.

In operations 206 and 208, the vehicular medical assistant can implement a mitigation action in response to detecting the medical event. In some embodiments, the mitigation action comprises interacting with the passenger (e.g., operation 206) and/or modifying the vehicle (e.g., operation 208). As shown, operations 206 and 208 can occur approximately contemporaneously or sequentially according to various embodiments of the present disclosure. In some embodiments, aspects of operation 206 are related to aspects of operation 208 and vice versa. For example, in operation 208, the vehicular medical assistant can reroute the vehicle. In response to rerouting the vehicle, the vehicular medical assistant can notify the passenger that the vehicle is rerouted and indicate the new destination in operation 206.

In operation 206, the vehicular medical assistant can interact with the passenger in response to detecting the medical event. The vehicular medical assistant can interact with the passenger by communicating with the passenger (e.g., providing instructions to the passenger, asking the passenger health-related questions, providing a notification to the passenger, etc.) and/or providing medical aids to the passenger (e.g., a bandage, an antiseptic, a disinfectant, an epinephrine autoinjector, an opiate antidote, an inhaler, etc.). Operation 206 is described in more detail hereinafter with respect to FIG. 8.

In operation 208, the vehicular medical assistant can modify the vehicle based on the detected medical event. The vehicular medical assistant can modify the vehicle by, for example, altering the temperature of the vehicle, rerouting the vehicle to an emergency facility, notifying an emergency authority of the medical event, requesting assistance from bystanders regarding the medical event, and so on. Operation 208 is described in more detail hereinafter with respect to FIG. 9.

FIG. 2 is intended to represent the major operations of an example method for managing a medical event according to embodiments of the present disclosure. In some embodiments, however, individual operations can have greater or lesser complexity than shown in FIG. 2, and operations other than, or in addition to, those shown in FIG. 2 can be present. Furthermore, in some embodiments, various operations illustrated in FIG. 2 can have greater, lesser, or different functionality than shown in FIG. 2.

FIG. 3 illustrates a flowchart of an example method for generating a medical event index in accordance with some embodiments of the present disclosure. In some embodiments, the method 300 is executed by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10), by a processor, or by a different set of hardware and software resources. For clarity, the method 300 will be described as being executed by a vehicular medical assistant, however, the method 300 can likewise be performed by alternative configurations of hardware. In some embodiments, the method 300 is a sub-method of operation 202 of FIG. 2.

In operation 302, the vehicular medical assistant can retrieve a medical corpus. The medical corpus can comprise structured and unstructured data relevant to identifying and mitigating medical events in a vehicular environment. The medical corpus can comprise diagnostic data (e.g., diagnostic data 122 of FIG. 1), medical condition data (e.g., medical conditions 124 of FIG. 1), and/or mitigation data (e.g., mitigation actions 126 of FIG. 1).

In operation 304, the vehicular medical assistant retrieves passenger medical information. The vehicular medical assistant can collect passenger medical information such as, but not limited to, historical medical diagnostics (e.g., blood pressure readings, heart rate readings, diseases, conditions, symptoms, risk factors, etc.). In some embodiments, the vehicular medical assistant can retrieve passenger medical information from one or more passenger devices (e.g., passenger device 136 of FIG. 1). In some embodiments, the vehicular medical assistant can retrieve the medical information from a database storing the medical information of the passenger (e.g., an electronic health record).

For example, in some embodiments, the passenger could be a subscribing member to a ride-sharing service associated with the vehicle. The passenger could input his/her fingerprint into the system upon entering the vehicle. The fingerprint could be used to identify the passenger, generate invoicing, determine preferred routes, determine likely destinations, and store a history of the passenger's medical information. Thus, the vehicular medical assistant could retrieve passenger medical data based on a biometric identification of the passenger. Although a fingerprint was used in the previous example, alternative biometric identifiers are also possible. For example, eye characteristics, facial recognition, voice recognition, or a different factor or combination of factors could be used to identify a passenger.

In operation 306, the vehicular medical assistant can perform cognitive learning on the accumulated data (e.g., the data collected in operation 302 and/or the data collected in operation 304). The vehicular medical assistant can perform cognitive learning on the medical corpus and/or the passenger medical information to characterize normal and abnormal ranges of various health diagnostics, emergent health conditions, effective mitigation techniques for various emergent health conditions, and/or other interrelationships, correlations, indicators, predictors, confidence levels, and other insights relating diagnostic data, medical condition data, and mitigation actions.

Although not shown, the vehicular medical assistant can execute any number of machine learning algorithms such as, but not limited to, decision tree learning, association rule learning, artificial neural networks, deep learning, inductive logic programming, support vector machines, clustering, Bayesian networks, reinforcement learning, representation learning, similarity/metric training, sparse dictionary learning, genetic algorithms, rule-based learning, and/or other machine learning techniques.

For example, the vehicular medical assistant can be configured to perform machine learning using one or more of the following example techniques: K-nearest neighbor (KNN), learning vector quantization (LVQ), self-organizing map (SOM), logistic regression, ordinary least squares regression (OLSR), linear regression, stepwise regression, multivariate adaptive regression spline (MARS), ridge regression, least absolute shrinkage and selection operator (LASSO), elastic net, least-angle regression (LARS), probabilistic classifier, naïve Bayes classifier, binary classifier, linear classifier, hierarchical classifier, canonical correlation analysis (CCA), factor analysis, independent component analysis (ICA), linear discriminant analysis (LDA), multidimensional scaling (MDS), non-negative metric factorization (NMF), partial least squares regression (PLSR), principal component analysis (PCA), principal component regression (PCR), Sammon mapping, t-distributed stochastic neighbor embedding (t-SNE), bootstrap aggregating, ensemble averaging, gradient boosted decision tree (GBRT), gradient boosting machine (GBM), inductive bias algorithms, Q-learning, state-action-reward-state-action (SARSA), temporal difference (TD) learning, apriori algorithms, equivalence class transformation (ECLAT) algorithms, Gaussian process regression, gene expression programming, group method of data handling (GMDH), inductive logic programming, instance-based learning, logistic model trees, information fuzzy networks (IFN), hidden Markov models, Gaussian naïve Bayes, multinomial naïve Bayes, averaged one-dependence estimators (AODE), Bayesian network (BN), classification and regression tree (CART), chi-squared automatic interaction detection (CHAID), expectation-maximization algorithm, feedforward neural networks, logic learning machine, self-organizing map, single-linkage clustering, fuzzy clustering, hierarchical clustering, Boltzmann machines, convolutional neural networks, recurrent neural networks, hierarchical temporal memory (HTM), and/or other machine learning techniques.

In operation 308, the vehicular medical assistant can generate a medical event index based on the machine learning algorithms implemented in operation 306. The medical event index can interrelate various diagnostic data, medical conditions, and mitigation actions. The medical event index is discussed in more detail hereinafter with respect to FIG. 4 and FIGS. 5A-5C.

FIG. 3 is intended to represent the major operations of an example method for generating a medical event index according to embodiments of the present disclosure. In some embodiments, however, individual operations can have greater or lesser complexity than shown in FIG. 3, and operations other than, or in addition to, those shown in FIG. 3 can be present. Furthermore, in some embodiments, various operations illustrated in FIG. 3 can have greater, lesser, or different functionality than shown in FIG. 3.

FIG. 4 illustrates an example medical event index in accordance with some embodiments of the present disclosure. In some embodiments, the medical event index 400 is generated by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10). In other embodiments, the medical event index 400 is generated by an outside service and provided to the vehicular medical assistant via a physical or wireless network (e.g., network 150 of FIG. 1). In some embodiments, the medical event index 400 is consistent with the medical event index generated in operation 308 of FIG. 3 and/or medical event index 128 of FIG. 1.

Medical event index 400 can include relationships between notifications 402, medical risk assessment values 404, and vehicle actions 406. Medical risk assessment values 404 can be based on diagnostic data collected by the vehicular medical assistant (e.g., data collected from aural sensors, biometric sensors, visual sensors, and/or environmental sensors). In some embodiments, the medical risk assessment values 404 range from 0 (no medical event) to 100 (severe medical event). However, alternative ranges and/or scales can be used in alternative embodiments. Medical risk assessment values 404 are discussed in more detail hereinafter with respect to FIG. 5A.

Notifications 402 can include notifications to a passenger, an emergency contact, and/or an emergency authority (e.g., hospitals, urgent care centers, law enforcement, etc.). Notifications can be issued visually, verbally, and/or textually on an interface in a vehicle, to a dispatch center associated with an emergency authority, to a mobile phone associated with the passenger (or to a mobile phone of an emergency contact associated with the passenger), and/or to a wearable device associated with the passenger.

Vehicle actions 406 can include additional diagnostic actions, mitigation actions, and/or notification actions. Diagnostic actions can include collecting additional data (e.g., verifying an abnormal health condition), collecting additional types of data (e.g., requesting a diabetic passenger undergo a blood sugar test in response to detecting the passenger may be experiencing abnormal blood sugar levels), interacting with the passenger (e.g., asking the passenger a health-related question), or other diagnostic actions.

Mitigation actions can include rerouting the vehicle, altering the environmental conditions of the vehicle cabin, contacting an emergency authority, dispensing a medical aid to the passenger, notifying bystanders of the medical event, or other mitigation actions.

The medical event index 400 can include a variety of rules interrelating medical risk assessment values 404 with vehicle actions 406 and notifications 402. In a first example rule 408, there is no notification and no action associated with a score less than or equal to 25. In a second example rule 410, there is no notification but additional diagnostic testing with a score greater than 25 and less than or equal to 50. In a third example rule 412, the passenger is notified, and the vehicle performs a mitigation action for scores greater than 50 and less than or equal to 75. In a fourth example 414, the passenger is notified, an emergency service is notified, and a mitigation action is performed for scores greater than 75 and less than or equal to 100. In a fifth example 416, a false alarm is identified according to custom rules, the passenger is notified, and any mitigation actions are rescinded. In a sixth example 418, a diagnostic action and/or a mitigation action is postponed according to custom rules, and the passenger is notified. In a seventh example 420, a diagnostic action and/or a mitigation action is rescheduled according to custom rules, and the passenger is notified.

As will be appreciated by one skilled in the art, the example medical event index 400 illustrated in FIG. 4 can have alternative rules, ranges, scores, notifications, and actions while remaining within the spirit and scope of the present disclosure. Furthermore, some embodiments (e.g., embodiments based on neural networks) can comprise no table at all but rather a model that ingests data from sensors and outputs a score, a notification, a diagnostic action, and/or a mitigation action while remaining within the spirit and scope of the present disclosure.

FIGS. 5A-5C illustrate example data tables configured to collect data, score data, identify medical conditions, and select mitigation actions. In some embodiments, FIGS. 5A-5C are associated with medical event index 400 of FIG. 4. In some embodiments, FIGS. 5A-5C perform aspects of operation 202 of FIG. 2 and/or perform aspects of the method 300 of FIG. 3. The tables illustrated in FIGS. 5A-5C can be generated and maintained by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or 1000 of FIG. 10) or a different configuration of hardware and/or software.

FIG. 5A illustrates an example medical risk assessment value table 500. The medical risk assessment value table 500 can include sensors 502 associated with collected data 504, normal values 506, concerned values 508, emergency values 510, and scores 512. Sensors 502 can comprise sensors associated with a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or 1000 of FIG. 10). In some embodiments, respective sensors 502 can be consistent with aural sensors 104, biometric sensors 106, visual sensors 108, and/or environmental sensors 110 of FIG. 1.

Data 504 can comprise data collected from sensors 502. The collected data can comprise numeric data (e.g., temperatures, blood pressures, heart rate, etc.), categorical data (e.g., normal or abnormal gesticulations), textual data (e.g., voice to text processing), and/or other data.

Normal values 506 can be typical values indicating stable health. Concerned values 508 can indicate ranges of values from sensors 502 associated with possible medical events. Concerned values 508 may not qualify as a medical event in isolation, but taken together with other values may indicate an emergent medical event. Emergency values 510 can comprise a range of values associated with respective sensors 502 that can indicate a medical event.

Scores 512 can comprise arithmetic and/or algebraic functions using data 504 as input. As shown, respective scores 512 for respective sensors 502 can include at least a weight value (e.g., W1 through WN) and a function (e.g., F1 through FN) utilizing a measured value (e.g., X1 through XN) from data 504.

Although individual scores 512 are shown, scores 512 can also be combined to generate an overall score. Individual scores 512 associated with respective sensors 502 (e.g., sub-scores) can be combined with other individual scores arithmetically (e.g., summed, etc.), algebraically (e.g., weighted, normalized, etc.), or using a different method. In some embodiments, scores 512 (or combinations of scores 512) can be used as medical risk assessment values 404 in the medical event index 400 of FIG. 4.

In some embodiments, normal values 506, concerned values 508, emergency values 510, and/or scores 512 can be defined based on cognitive learning performed on a corpus of medical data (e.g., operation 306 of FIG. 3).

For the purposes of illustration and as non-limiting examples, medical risk assessment value table 500 can include a first row 514 collecting a reading of 98 from a directional thermometer (e.g., biometric sensor) associated with a normal range 506, a concerned range 508, and an emergency range 510 which can be used to generate a score 512. As another example, a second row 516 can collect a reading of 18 corresponding to a number of blinks per minute collected from a camera (e.g., visual sensor) and associated with a normal range 506, a concerned range 508, an emergency range 510 which can together be used to generate a score 512. As another example, a third row 518 can classify passenger gesticulations collected from a camera (e.g., visual sensor) and associated with a set of normal gesticulations 506, a set of concerned gesticulations 508 (e.g., tremors), a set of emergency gesticulations 510 (e.g., hands on throat) which can together be used to generate a score 512. As another example, a fourth row 520 can collect verbal data using a microphone (e.g., aural sensor) and associated with a normal vocabulary 506, a concerned vocabulary 508 (e.g., the phrase “I'm not feeling well”), an emergency vocabulary (e.g., the phrase “help me”) which can together be used to generate a score 512.

FIG. 5B illustrates an example medical condition table 522. Medical condition table 522 can include any number of medical conditions 524 such as, but not limited to, unconscious, fever, nauseous, choking, heart attack, and so on. Respective medical conditions 524 can be associated with respective sensor data rules 526. Sensor data rules 526 can be ranges (or combinations of ranges) of numeric data, types of categorical data (e.g., agitated gesticulation, abnormal heart rate, etc.), and/or specific phrases (e.g., a passenger saying “help”, a retching sound, etc.).

In some embodiments, sensor data rules 526 can be compared with data 504 collected from sensors 502 to determine medical conditions 524. In some embodiments, medical conditions 524 comprise part of a notification 402 and/or part of a medical risk assessment value 404 as discussed in the medical event index 400 of FIG. 4.

FIG. 5C illustrates an example mitigation action table 528. Mitigation action table 528 can include any number of mitigation actions 530 executable by a vehicular medical assistant such as, but not limited to, attempting to wake a passenger using vehicle speakers, rerouting a vehicle, engaging emergency sirens and/or lights, requesting assistance using external speakers, notifying an emergency authority, increasing or decreasing the vehicle's cabin temperature, dispensing a medical aid, and so on. Respective mitigation actions 530 can be triggered by respective conditions 532. Respective conditions 532 can be based on medical conditions 524 and/or scores 512.

FIGS. 5A-5C are intended to represent the major components of example data tables configured for monitoring passenger health, scoring diagnostic data, identifying medical conditions, and/or selecting mitigation actions in accordance with embodiments of the present disclosure. In some embodiments, however, aspects of the data tables presented in FIGS. 5A-5C can have greater or lesser complexity than shown, and data tables other than, or in addition to, those shown in FIGS. 5A-5C can be present. Furthermore, in some embodiments, aspects of the data tables illustrated in FIGS. 5A-5C can have greater, lesser, or different functionality than shown in FIGS. 5A-5C.

FIG. 7 illustrates a flowchart of an example method for detecting a medical event using data tables in accordance with some embodiments of the present disclosure. In some embodiments, the method 700 is executed by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10), by a processor, or by a different set of hardware and software resources. For clarity, the method 700 will be described as being executed by a vehicular medical assistant, however, the method 700 can likewise be performed by alternative configurations of hardware. In some embodiments, the method 700 is a sub-method of operation 204 of FIG. 2. In some embodiments, the method 700 is a sub-method of operation 604 of FIG. 6.

In operation 702, the vehicular medical assistant can collect sensor data in a medical risk assessment value table (e.g., the medical risk assessment value table 500 of FIG. 5A). In some embodiments, operation 702 comprises storing sensor data in the medical risk assessment value table at each predetermined increment of time (e.g., each 1 second, 5 seconds, 10 seconds, 30 seconds, etc.).

In operation 704, the vehicular medical assistant can calculate a medical risk assessment value based on the data collected in the medical risk assessment value table in operation 702 (e.g., based on aural data, biometric data, visual data, and/or environmental data). The medical risk assessment value score can comprise one or more sub-scores calculated for respective sensors. Respective sub-scores can be associated with respective weights and/or respective functions.

FIG. 8 illustrates a flowchart of an example method for interacting with a passenger during a medical event in accordance with some embodiments of the present disclosure. In some embodiments, the method 800 is executed by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10), by a processor, or by a different set of hardware and software resources. For clarity, the method 800 will be described as being executed by a vehicular medical assistant, however, the method 800 can likewise be performed by alternative configurations of hardware. In some embodiments, the method 800 is a sub-method of operation 206 of FIG. 2.

In operation 802, the vehicular medical assistant can communicate with the passenger. The vehicular medical assistant can communicate with the passenger verbally, textually, and/or visually in order to ask a question (e.g., gather additional health-related data), present instructions (e.g., indicate how to ameliorate a medical event), and/or provide a notification (e.g., indicate that an emergency authority was contacted and the vehicle was rerouted). For example, the vehicular medical assistant can communicate with the passenger using automated voice software to verbally ask the passenger a question. As another example, the vehicular medical assistant can present a textual question on a display device. As another example, the vehicular medical assistant can communicate with a passenger by presenting diagrammatic, pictographic, videographic, or other visual communications on a display device.

The vehicular medical assistant can receive feedback from the passenger verbally, tactilely, or otherwise. For example, the passenger can verbally respond to a question and the vehicular medical assistant can use voice-to-text software or other software to convert the verbal feedback to ingestible information. As another example, the passenger can interact with the vehicular medical assistant by providing tactile feedback such as, but not limited to, typing an answer, pushing a button on a touch screen, or performing a medical diagnostic test (e.g., by placing the passenger's arm in a blood pressure cuff).

In operation 804, the vehicular medical assistant can dispense a medical device to the passenger. Medical devices can include, but are not limited to, a bandage, an antiseptic, a disinfectant, a vomit bag, a medication, an epinephrine autoinjector, an opiate antidote, an inhaler, and/or a different medical device.

In operation 806, the vehicular medical assistant can record the interaction. For example, the vehicular medical assistant can notate the time, type, and reasoning (e.g., calculated scores, detected medical conditions, raw sensor data, etc.) for a dispensed medical aid together with a video showing the passenger consuming, applying, or otherwise using the dispensed medical aid. In some embodiments, operation 806 can further comprise sending the recording of the interaction, information regarding the passenger, information regarding the medical event, and/or information regarding the medical aid to an emergency authority.

In some embodiments, the recorded interaction is automatically encrypted. The recorded interaction can be automatically encrypted using a public-key encryption scheme (e.g., Diffie-Hellman encryption, Rivest-Shamir-Adleman (RSA) encryption, etc.), a symmetric-key encryption scheme (e.g., Data Encryption Standard (DES), triple-DES, Advanced Encryption Standard (AES), Rivest Cipher 4 (RC4, ARC4, or ARCFOUR), hash functions (e.g., MD4, MD5, SHA-1, SHA-2, etc.)), Schnorr signature encryption, El-Gamal encryption, Pretty good Privacy (PGP) encryption, interactive proof encryption, and/or other encryption schemes.

In some embodiments, the recorded interaction includes updating an immutable, distributed ledger (e.g., a blockchain) associated with the passenger medical history and/or a dispensed medical aid. For example, in some embodiments, a date, time, location, passenger identification, and passenger diagnostic data can be stored in an immutable, distributed ledge associated with the dispensed medical aid. In some embodiments, a date, time, location, passenger diagnostic data, and any vehicular actions or interactions can be recorded in an immutable, distributed ledger associated with the passenger identification and accessible to healthcare practitioners (e.g., an electronic health record).

FIG. 8 is intended to represent the major operations of an example method for interacting with a passenger during a medical event according to embodiments of the present disclosure. In some embodiments, however, individual operations can have greater or lesser complexity than shown in FIG. 8, and operations other than, or in addition to, those shown in FIG. 8 can be present. Furthermore, in some embodiments, various operations illustrated in FIG. 8 can have greater, lesser, or different functionality than shown in FIG. 8.

FIG. 9 illustrates a flowchart of an example method for modifying a vehicle during a medical event in accordance with some embodiments of the present disclosure. In some embodiments, the method 900 is executed by a vehicular medical assistant (e.g., vehicular medical assistant 102 of FIG. 1 or vehicular medical assistant 1000 of FIG. 10), by a processor, or by a different set of hardware and software resources. For clarity, the method 900 will be described as being executed by a vehicular medical assistant, however, the method 900 can likewise be performed by alternative configurations of hardware. In some embodiments, the method 900 is a sub-method of operation 208 of FIG. 2.

In operation 902, the vehicular medical assistant can modify a route of the vehicle. For example, in a non-autonomous vehicle, a new vehicle route can be presented on navigation equipment in the non-autonomous vehicle for the driver to follow. In a semi-autonomous vehicle, the vehicle can be autonomously rerouted to the side of the road and stopped. In an autonomous vehicle, the vehicle can be rerouted directly to a hospital, a clinic, a police station, a fire station, a rendezvous point, or a different location using autonomous driving features of the vehicle. In some embodiments, the vehicular medical assistant can calculate an estimated time of arrival based on the new route.

In some embodiments, the vehicular medical assistant can interact with a traffic service (e.g., traffic service 132 of FIG. 1) to choose between multiple locations based on estimated traffic condition (e.g., a first hospital may be geographically closer than a second hospital, but when accounting for traffic, the second hospital may be associated with an earlier arrival time than the first hospital). In such embodiments, the traffic service can be used to estimate an updated time of arrival accounting for traffic. In some embodiments, the traffic service deploys traffic shaping actions (e.g., traffic light manipulation, presenting notifications on electronic roadway signs, etc.) to reduce traffic delays associated with the route.

In some embodiments, the vehicular medical assistant can interact with a mobile emergency unit (e.g., mobile emergency unit 134) in order to create a rendezvous point between the vehicle and the mobile emergency unit.

In some embodiments, operation 902 further comprises notifying a destination (e.g., a hospital, a clinic, an emergency center, etc.) associated with the new route by providing an estimated time of arrival and/or information associated with the medical event.

In operation 904, the vehicular medical assistant can modify the vehicle environment. For example, the vehicular medical assistant can alter a cabin temperature of the vehicle by modifying a temperature control and/or a fan speed control of the heating and cooling system of the vehicle. As another example, the vehicular medical assistant can increase the noise level in the cabin of the vehicle in order to attempt to wake an unconscious or semi-conscious passenger.

In operation 906, the vehicular medical assistant can deploy one or more emergency protocols. Emergency protocols can include, but are not limited to, contacting an emergency authority (e.g., emergency service 130 of FIG. 1), turning on external hazard indicators, and/or requesting bystander help. An emergency authority can be contacted by broadcasting, calling, emailing, transmitting an emergency code, or otherwise notifying the emergency authority. External hazard indicators can include, but are not limited to, lights, sirens, and speakers. Requesting bystander help can include indicating the nature of the medical event using an external speaker and/or broadcasting the nature of the medical event to surrounding vehicles via a wireless broadcasting technique.

Wireless broadcasting techniques can include, but are not limited to, ANT/ANT+, Bluetooth, cellular (e.g., 3G, 4G, 5G, etc.), infrared, the Industrial, Scientific, and Medical (ISM) band, 6LoWPAN, ultra-wideband (UWB), Wi Fi, wirelessHART, WirelessHD, techniques conforming to Institute of Electrical and Electronics Engineers (IEEE) standards such as IEEE 802.15.4 and IEEE 802.22, techniques conforming to International Standards of Automation (ISA) standards such as ISA100a, and/or different techniques.

FIG. 9 is intended to represent the major operations of an example method for modifying a vehicle during a medical event according to embodiments of the present disclosure. In some embodiments, however, individual operations can have greater or lesser complexity than shown in FIG. 9, and operations other than, or in addition to, those shown in FIG. 9 can be present. Furthermore, in some embodiments, various operations illustrated in FIG. 9 can have greater, lesser, or different functionality than shown in FIG. 9.

Furthermore, in some embodiments, various components illustrated in FIG. 10 can have greater, lesser, or different functionality than shown in FIG. 10.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 11, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 11 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
